The S8’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The GS F doesn’t offer pre-crash pretensioners.

Both the S8 and GS F have child safety locks to prevent children from opening the rear doors. The S8 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The GS F’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The S8 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The GS F doesn’t offer front seat center airbags.

The S8 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The GS F doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

The S8 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The GS F doesn’t offer all-wheel drive.

A passive infrared night vision system optional on the S8 helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard and even aims one of the vehicle’s headlights in the direction of the person or object. The GS F doesn’t offer a night vision system.

The S8 has a standard Top View Camera System to allow the driver to see objects all around the vehicle on a screen. The GS F only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the S8 and the GS F have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems and rear cross-path warning.

The Audi S8 weighs 1268 pounds more than the Lexus GS F. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

The S8’s corrosion warranty is 6 years longer than the GS F’s (12 vs. 6 years).

There are over 26 percent more Audi dealers than there are Lexus dealers, which makes it easier should you ever need service under the S8’s warranty.

The S8’s 4.0 turbo V8 hybrid produces 96 more horsepower (563 vs. 467) and 201 lbs.-ft. more torque (590 vs. 389) than the GS F’s 5.0 DOHC V8.

Regenerative brakes improve the S8’s fuel efficiency by converting inertia back into energy instead of wasting it. The GS F doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the S8’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The GS F doesn’t offer an automatic engine start/stop system.

The S8 has 4.3 gallons more fuel capacity than the GS F (21.7 vs. 17.4 gallons), for longer range between fill-ups.

The S8 offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The GS F doesn’t offer ceramic brake rotors.

For better traction, the S8 has larger tires than the GS F (265/40R20 vs. 255/35R19).

For better ride, handling and brake cooling the S8 has standard 20-inch wheels. Only 19-inch wheels are available on the GS F. The S8 offers optional 21-inch wheels.

The front and rear suspension of the S8 uses air springs for a smoother, controlled ride than the GS F, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The S8 has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The S8’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The GS F doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the S8’s wheelbase is 11 inches longer than on the GS F (123.2 inches vs. 112.2 inches).

For better handling and stability, the track (width between the wheels) on the S8 is 2.9 inches wider in the front and 2.3 inches wider in the rear than on the GS F.

The design of the Audi S8 amounts to more than styling. The S8 has an aerodynamic coefficient of drag of .29 Cd. That is significantly lower than the GS F (.33) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the S8 get better fuel mileage.

The S8 uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The GS F doesn’t offer active noise cancellation.

The S8 has .3 inches more front headroom, .9 inches more front legroom, 1.9 inches more front shoulder room, .7 inches more rear headroom, 11.5 inches more rear legroom and 1.9 inches more rear shoulder room than the GS F.

For enhanced passenger comfort on long trips the S8’s available rear seats recline. The GS F’s rear seats don’t recline.

To make loading and unloading groceries and cargo easier when your hands are full, the S8’s power trunk can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The GS F doesn’t offer a power or hands-free opening trunk.

Power rear and rear side window sunshades are standard in the S8 to help block heat and glare for the rear passengers. The GS F doesn’t offer rear side window sunshades.

Both the S8 and the GS F have standard heated front seats. The S8 also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the GS F.

The S8 has standard front air-conditioned seats and offers them optionally in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The GS F doesn’t offer air-conditioned seats in the rear.

On extremely cold winter days, the S8’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The GS F doesn’t offer a heated steering wheel.

The S8 has standard massaging front and optional massaging rear seats. Massaging seats aren’t available in the GS F.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Audi S8 has a standard wireless phone charging system (Qi) in the center console. The GS F doesn’t offer wireless personal charging.

The S8 offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The GS F doesn’t offer a house-current electrical outlet.
